My invention. relates to window washing machines and one object is toprovide a 1 chine.

portable machine of this character whereby windows may be washed withoutrequiring the operator to'stan'd upon' the outside of the 1 indow sillwhere" he would be more. or less in d nger of falling and becoming seri-:J Y a.

' I A'further object is to provide a substantial and efficient machineof this character which can I be manufactured I and marketed at areasonable price.

Other objects will hereinafter appear and in order that the inventionmay be fully understood, reference v will now be had to the accompanyingdrawings, in which "Fig. 1 is a broken vertical section of a window withthe machine in position for .washing the glass in the upper sash.

" Fig. 2 is a plan view of the machine. Fig. 3 is a front elevationFig.4 is a section on line 4-4 of Fig. 2. Fig. 5 is a broken crosssection on line 5 of Fig 1 showing means for securing the front portionof the machine to a window Fig. 6 is a detail plan View of a mopemployed in carrying out the invention.

Fig. 7 is an end elevation of the machine equipped with anelectric'motor for driving the mop actuating mechanism.

In carrying out the invention I-employ atelescopic frame 2 consisting ofa primary section 4 and a secondary section 6' which are slidably.connected so that .the' frame may be extended or contracted to fitwindow sills of different widths. The primary sec- 'tion 4 is providedat its lower rear portion with one or more depending brackets 3 having alike number of set screws 5 adapted to engage the rear ledge A of thewindow sill B. i "The secondary section 6 is provided with a hook 7adapted to engage under the front ledge C ofthe window sill B and thuscoact with the set screws 5 in firmly securing the frame 2 in position.

1 The hook 7 is secured" to a block 9 which is provided with grooves 11which receive the lower flanges on the secondary frame, asshown by Fig.5. The foregoing arrangement permits the hook 7 and the block of the ma-P y with a. fixedly mounted cog wheel 28 which mtermeshes with arack3O'fixed upon a ary the lower angle bars of 9 to be lid backwardlyandforwardly upon the secondary frame section widths so "that it will"not b'ei necessary to The forward end of the secondary frame sect1o'n6is equipped with afixed segmental plate 8,- against which av moveable 1segmental 10 is heldby-guides 12 secured to' said fixed plate 8. Thesegmental plate 10'. is 'ii ockable about the axisdf *afdr-ivelshaft 13en tending longitudinally of the frame 2 and 'journaled in bearings 14and 16, at therear and front portions of the primary and secondarysect1ons'4 and 6, respectively. The

drive shaft 13 is provided at itsjrear end with a crank 20fwhereby itmay be manually rotated and isprovided atits forward end with a fixedlymounted bevel gear 21 which intermeshes with a bevel. gear 22 fixedlymounted upon a counter-shaft 24 journaled 111 bearings 26 mounteduponthe rockable' late 10. The countershaft 24 is provided bar 31'1whichis reciprocably mountedlin a,

guide 32 carried by a yoke 34- rockably mounted upon the countershaft24.

The bar '31 is provided at its upper end with amop, orother suitablewindow clean-.

ing device 35 whichiincludes a back plate 36 and a clevis, 38, whichlatter is connected to the former by a pivot/39 and connected totheupper end of the bar 31 by'a pivot 40. In practice "the frame 2*isfitted to th'e window sill B either by adjusting the hook i 7 and theblock 9 forwardly or backwardly or by adjusting the secondary framesection 6 forwardly or back-wardly. If the second section (iyisgadjustedthe drive shaft 13 moves backwardly or forwardly therewith andaccordingly "slides in the bearing 14.

After the fran'ie2 has been adjustedand secured to the window sill'Bthebar 31 is grasped over the outer glass D, while the crank 20 is rotatedin reverse direct-ionswith' the other hand to effect up anddownmovementwith one" hand to guide the mop of the mop to the top andbottom of said glass D. During the foregoing operation the mop can bemoved in any direction over 1 the window glass D due to the rockablemovementof the segmental plate 10, the yoke 34, and the pivots 39 and40.

VVhe'n the machine is equipped withwan electric motor 40? as shown byFig.7, it will not be necessary to operate the crank 20 by in; j

hand, as said motor 40, through the intermediary of the train of gears46, will act-uate the drive shaft 13, whichlatteris pro vided with aspline 48 so that it may slide through the large gear 50 of the train 46and at the same time be driven by said large gear. The motor 40" ispreferably oi the reversible type so that when the mop reaches the endof an upward stroke said motor may be reversed to effect a'down strokeof said mop, or any well known form of reversible gearing may beassociated with the train 4:6 for that purpose; ,1

F mm the itoregojing description it will be apparent that I have,provided a Window washing machine embodying the advantages above po ntedout, and while I have shown a preferred embodiment of the invention Ireserve all rights to such changes and modifications as properly fallwithin the spirit and scope of the invention as claimed.

Having thus described my I invention, what I claim and desire to secureby Letters Patent, is:

In a machine of the character described, a frame adapted to be securedto a Window sill, a window cleaning device, a rack, a guide for saidrack, a yoke to which said g'uide isfixed, a plate rockably mounted atthe forward portion'of the frame, and provided with hearings in which ashatfiis j ourna led, a gear wheel mounted upon said shaft fordrivingtlie rack, intermeshing bevel gears tor driving; said shaft, anda drive shaft mounted in the frame aud'up on which one 0t said bevel,gears. is IIlOLl l ltGd,

In testimony whereof I aflix my signature.
